Using an MSI RADEON 5770. Current hash is around 222 mh/s at 92 percent GPU usage. Core temp at 46C.

Current clock settings are(tweaked through MSI Afterburner):
1.25v
970 core clock
330 mem clock

with operator flags:

-k phatk DEVICE=0 AGGRESSION=6 VECTORS WORKSIZE=128 BFI_INT -a 1000 FASTLOOP=false

970 Core because any higher and I seem to freeze and overvolting past 1.25, Im told there are dragons past thar.

330 memclock since that seems to be when my speeds peak.

Interesting part is that Aggression 6 is where my hashes are the highest. 7 and 5 are about 15 to 20 mh/s slower. Often people recommend aggression 12 and that is slower by about 15 hash as well.

Increasing worksize to 256 seems to reduce hashing by about 2 hashes. Lowering it to 64 has almost no affect. fastloop seems to drop hashes by around 5.

I kind of get the sense that something is fishy here since at 6 aggression my desktop experience is barely affected at all and raising it or lowering it reduces my hashes. Also not sure about why I cant overclock more and be stable. Also 44C is really really cold which actually frustrates me since I figure I have that much more OCing potential in this card that I am not making use of.

Also noteworthy is that at Aggression 6 I have full control of my desktop still.
